Mathematical model for assessing the shortage of crops from overconsolidation of the soil by the movers of agricultural machines

Abstract

The researches of impact assessment of agricultural machines’ movers are done in all countries with the use of mobile energy vehicles, which are used for the rolling of the soil with different multiplicity of passes through the fields. Mathematical model is developed taking into account the adding of arable and subsurface layers’ impact on field productivity. It allows one to predict the yield of crops based on impact of agricultural vehicles that perform technological operations, taking into account the width of the track, width of the unit and overlap area. Method of correct determination of indicators of mathematical model is developed. It includes adjustment of the density of the soil layer 0-40 cm and maximum yield value, the exponent of the model. It also includes determination of the coefficients included in it the transformed equation, which corresponds to the mathematical model, after substitution of these indicators in it.  Evaluation of the effectiveness of the pressure of the rear tyres of the beet harvester RKM-6 reduction is performed. The pressure became lower by replacing the tires 21,3-24 on the tires 21,3-26 with data on the change in the soil density in 0-20 and 20-40 cm layers where the RKM-6’s tracks.
